FIRE-EXTINGUlSHER.

SPECIFICATION forming part of Letters Patent No. 388,773, dated August28, 1888.

Application filed February 11, 1887- Serinl No. 227,990.. (No model.)

T 0 all whmwit may concern.-

Be it known that I, lsiiilo N. GOODNIGI-IT, a citizen of the UnitedStates, residing at Kempton, in the county of Tipton and State ofIndiana, have invented certain new and useful Improvements inFire-Extinguishers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is attached to stoves in railroad cars; and the object is'to extinguish the fire in the stove in case of accident to the car.

In the accompanying drawings, Figure 1 represents a vertical sectionalview of my invention connected with the stove; Fig. 2, a verticalsectional view of a modification of my invention, and Fig. 3 a top viewof my device, as shown in Fig. 1.

. Siinilarletters refer to similar parts throughout the several views.

0 is a stationary case or frame elevated above the stove.

H is a reservoir within the case, and is at tached to the case by thepins t in such a manner as to allow the reservoir to swing freely on thepins. The reservoir is connected with the stove I by the flexible tube71., and the connection is closed at will by the valve A at the mouth ofthe tube and bottom of the reservoir. This valve A is attached to thetube 13 and moves with it. The tube B is held by suitable guides, so asto insure a proper adj ustmcnt of the valve. The connection between thereservoir and stove is closed by the valve A, which is held firmlyagainst the mouth of the tube h in the following manner: The cord orchain 0 is fastened to the tube B, and passes down and around the fixedpulley D, and thence up through the tube 13 to the drum E, over which itis wound and held at any desired tension by the pawl F. \Vhen the cord Gis loosened, the valve is instantly opened by the spring G, which is soarranged as to be constantly pressing on the valve with a tendency toopen it.

' the car.

Mis a chain attached to the pawl F and attached at each end to the sidesof the frame 0.

The practical operation of my device is as follows: The case or frame 0is attached to and partakes 0f the motion of the car. Vihen the valve Ais closed and the reservoir H filled with water or other extinguishingagent, the principal weight will be below the center of suspension t,and will cause the reservoir to maintain a vertical position. When anaccident occurs and the car is thrown from the track, the frame 0,turning with the car, and the reservoir, remaining in a verticalposition, will cause the chain M to force the pawl F off of the ratchete on the drum E, thereby loosening the cord or chain 0. The valve willthus be opened by the spring G, and the water will flow into the stove,extinguishing the fire. The chain M is made slack enough to allow forany ordinary tipping of In the modification drawn in Fig. 2 the spring,pulley, 850., are placed higher up, in order to leave the mouth of thetube It free for the passage of the glass grenades T, which may be usedin the place of water.

The tube B, to which is attached the valve A, will, in practice, he soconstructed and arranged that it may be automatically raised to aconsiderable height to permit a genade to pass out between the valveinto the flexible tube h.

Having thus fully described my invention, what I claim as new, and wishto secure by Letters Patent, is

1. The combination, with the ear and the stove I, of a fire-extinguishercomprising the following elements, viz: the frame 0, secured to the carabove the stove, the reservoir H, pivoted within said frame, the tubeit, communicating with the reservoir and stove, the sliding tube B,valve A, attached to said tube and held down to close communicationbetween the reservoir and stove by cord or chain 0, fixed pulley D, drumE, pawl F, and the spring G, to operate upon the valve to press it openwhen the cord (J is loosened by the movement of the car, all constructedM and spring G for automatically opening 10 and arranged substantiallyas shown and dethe valve, all substantially as shown and described.scribed.

2. The swinging reservoir H, pivoted within In testimony whereof I affixmy signature in the frame 0, secured to the car, the stove I, presenceof two witnesses.

and the tube h, connecting the stove and reser- ISAAC N. GOODNIGH'I.voir, in combination with the valve A, the i Witnesses: cord 0, pulleyD, drum E, and ratchet F, all GHAs. D. EBERT,
